Yeah, in the case of Mordo, in the comic books, that character was just really arch.
You know, just really arch and he’s in the origin issue and even in reading through – and I’ve read the entire body of Doctor Strange now – it was a difficult character, very difficult character to adapt. Because of the very basic archness that he plays all the way through there.
So we wanted to keep what were the interesting aspects of him (his relationship with The Ancient One) but the only way that Mordo, who needs to be a presence in the universe of Doctor Strange and God willing, in sequels.
I felt that we had to start by establishing who he was before he got into that arch villainy in the comics.
And that’s a lot of what we’re doing in this movie is we’re sort of building a foundational understanding of who he was before the guy that you met in that comic so that that turn isn’t an arch turn.
"[Mordo] is Strange’s advocate in the beginning of the movie. The Ancient One doesn’t necessarily see the potential in Strange that Mordo does, and Mordo is the one who talks the Ancient One into allowing him in. And for this film, he is a partner of Strange, and he is a mentor to Strange.
You know that was something we wanted to play against in the comics. Because in the comics for as unbelievably creative and full of imagination as they are – we are desperate to recreate in cinematic form – there’s some things that are too obvious for modern day audiences.
The jealous rival named Baron von Mordo, who turns against him when he shows any signs of talent – we specifically didn’t want to do that."
